I have a friend that insists that CAI on stock motors/tuning will actually lower performance and run more rich I can not see how that can be true because wouldn't the MAF detect the extra incoming air and adjust the a/f ratio???

 

Im thinking about getting a CAI on my Astro Van for increased economy/towing power...So this is why i ask.

 

Your friend is wrong, less restriction and more air = more power
and they make kits for astro vans!?! whats the world coming 2.

your friend is WRONG....trade him in for someone more intelligent.


easier air in equals more efficient motor...which is more power

cooler air in means a denser air charge, which means more o2 available to burn...which means more power.

the maf will adjust for the change

for the first few minutes its possible that the performance will be minimal, but once the computer learns the new settings and adjusts for it...you'll make more power.

decades of hotrodding can't be wrong

 

Wrong, and by the way show him this theard!

 

if anything you'd run leaner (if O2's were dead or not present)

 

Your friend is misinformed. Pop on the cold air intake and enjoy the modest power increase.
